Rather than calling virDomainHostdevAssignAddress during the parsing
of the XML, move the setting of a default hostdev address to domain/
device post processing.
Since the parse code no longer generates an address, we can remove
the virDomainDefMaybeAddHostdevSCSIcontroller since the call to
virDomainHostdevAssignAddress will attempt to add the controllers
that were not already defined in the XML.
This patch will also enforce that the address type is type 'drive'
when a SCSI subsystem <hostdev> element is provided with an <address>.

to set some sensible defaults, but it might get confusing for the user
as we don't do that for all controller models.

Since an mpath pool contains all the Multipath devices on a host, allowing
more than one defined on a host at a time should be disallowed under the
policy of disallowing duplicate source pools for the host.
Adjust to docs to clarify the Multipath target path value usage for both
the storage driver (only 1 pool per host) and formatstorage references
(ignore the target element in favor of the default target mapping of
/dev/mapper).

While re-reading what I wrote for commit id '785a8940e', I realized
I needed to clarify that being able to present as a 'lun', the mode
property for the pool source element needed to be "host" (or empty)
and not "direct".
It was described correctly later in the mode host description, but
this just ensures it's not missed here as well.

Also move the mention of version numbers for the various PCI
controller models up to the end of the sentence where they are first
given, to avoid confusion.
When support for the pcie-root and dmi-to-pci-bridge buses on a Q35
machinetype was added, I was concerned that even though qemu at the
time allowed plugging a PCI device into a PCIe port, that it might not
be supported in the future. To prevent painful backtracking in the
possible future where this happened, I disallowed such connections
except in a few specific cases requested by qemu developers (indicated
in the code with the flag VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG).
Now that a couple years have passed, there is a clear message from
qemu that there is no danger in allowing PCI devices to be plugged
into PCIe ports. This patch eliminates
VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG and changes the code to always
allow PCI->PCIe or PCIe->PCI connection *when the PCI address is
specified in the config. (For newly added devices that haven't yet
been given a PCI address, the auto-placement still prefers using the
correct type of bus).
In my previous fix (1310b1358) I've tried to solve an ordering
issue. Well, while it worked it has a side effect of keeping a
temporary file around. My patch was buggy in that sense. Solve
this by properly marking the dependency without any side effect.

Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
The virt-xml-validate tool fails with a similar error:
# virt-xml-validate lmb_guest.xml
Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :
Element domain failed to validate content
lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.

When generating the path to the dir for a CIFS/Samba driver, the code
would generate a source path for the mount using "%s:%s" while the
mount.cifs expects to see "//%s/%s". So check for the cifsfs and
format the source path appropriately.
Additionally, since there is no means to authenticate, the mount
needs a "-o guest" on the command line in order to anonymously mount
the Samba directory.
Commit id '887dd362' added support for a netfs pool format type 'cifs'
and 'gluster' in order to add rng support for Samba and glusterfs netfs
pools. Originally, the CIFS type support was added as part of commit
id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng
definition to match expectations.
As it turns out the CIFS rng needed a similar change since the directory
path is not an absDirPath, rather just a dirPath will be required.

Seems the property has been deprecated for qemu, although seemingly ignored.
This patch enforces from a libvirt perspective that a scsi-block 'lun'
device should not provide the 'serial' property.
https://bugzilla.redhat.com/show_bug.cgi?id=1228007
When attaching a scsi volume lun via the attach-device --config or
--persistent options, there was no translation of the source pool
like there was for the live path, thus the attempt to modify the config
would fail since not enough was known about the disk.
I see no reason to duplicate this list of architectures. This also allows
more guest architectures to be used with libvirt (like the mips64el qemu
machine I am trying to run).

The guest firmware provides the same functionality as the pvpanic

definition if it wasn't there already.
The guest firmware provides the same functionality as the pvpanic
device, which is not available in QEMU on pSeries, so the domain
XML should be allowed to contain the <panic> element.
On the other hand, unlike the pvpanic device, the guest firmware
can't be configured, so report an error if an address has been
provided in the XML.

The XML parser sets a default <mode> if none is explicitly passed in.
This is then used at pool/vol creation time, and unconditionally reported
in the XML.
The problem with this approach is that it's impossible for other code
to determine if the user explicitly requested a storage mode. There
are some cases where we want to make this distinction, but we currently
can't.
Handle <mode> parsing like we handle <owner>/<group>: if no value is
passed in, set it to -1, and adjust the internal consumers to handle
it.
- Don't redocument the permissions fields for backingstore, just point to
the volume docs.
- Clarify that owner/group are inherited from the parent directory at
volume create/pool build time.
- Clarify that <permissions> fields report runtime values too
